Thread: how would i pass on a vector pointer parameter

just a simple question...

i have this vector of a class

Code:

std::vector<PClass>* classes

but on a function i need this as a parameter

Code:

createClass(const & std::vector<PClass *>)

how could i pass my vector to this function?? would i do a long method in which creating a copy of vector of PClass pointers? or is there any other better solutions?

thanks and more power..

Huh? Did you mean to put the * outside the vector's <> because that would be a pointer to a vector. If you didn't you can do this.

Code:

#include <iostream>
#include <vector>

class Pclass
{
    int x;
};

void VecFunct(const std::vector<Pclass *> &vec)
{
    //do stuff
}

int main()
{
    std::vector<Pclass *> mainVec;
    
    VecFunct(mainVec);
    
    std::cin.get();
    
    return 0;
}

Can't be done, your vectors contain two different things, and are not interchangable.

Possibly, maybe you meant

Code:

std::vector<PClass*>* classes

in that case you could pass it like

Code:

createClass(*classes)

but the bottom line is that the thing inside the <brackets> must be the same.

Edit: I just read the last line of your post... yes you will have to copy a pointer of the object in the vecto to a new vector.

Edit 2: I thought I'd warn you to be careful with copying/using those pointers, because they could get out of sync with the original vector, for instance if you delete an elementof the original vector, the pointers will become invalid.
